Abstract

The utility model discloses a topdressing implement used under film, which is composed of an end cover with a handle provide with a center hole, a body tube and a cone fertilizer discharging mouth. The middle part of the body tube is provided with a fertilizer entering mouth, a connecting rod is arranged in the body tube, the upper part of the body tube is provided with a spring, the center hole of the end cover with a handle is penetrated by the upper end of the connecting rod, the top end of the connecting rod is provided with a transverse pull rod, the lower end of the connecting rod is provided with a plug valve, and the sizes and the positions of the plug valve and the cone fertilizer discharging mouth are corresponding. The utility model has the advantages of simple structure, easy production and small damage for mulching film at top dressing, and can satisfy the requirement of film laying cultivation crop during different growth period.

Description

Fertilizer placement drill under the film

The utility model relates to a kind of agricultural fertilizing device, especially relates to fertilizer placement drill under a kind of film.

Along with the development of agricultural production, adopt the crop of plastic mulching more and more, area is also increasing, has obtained good effect of increasing production and economic benefit.But plastic film mulching cultivation, it is very difficult that crops are imposed fertilizer in different growing stages, can not adopt conventional method.Topdress if method is spread fertilizer over the fields in employing, fertilizer is sprinkling upon on the film, is unfavorable for the crop absorption utilization; If trench digging row replacement or spread manuer in holes and then mulch film is caused major injury, and need many people co-operate.Therefore, how present plastic film mulching cultivation replaces and topdresses by strengthening the base manure consumption, and crops are in too prosperous length in early stage like this, because fertilizer deficiency, and influences output, the reduction benefit in the later stage.

It is little that the purpose of this utility model provides a kind of membrane damage over the ground, the crops that can satisfy plastic-film-covered cultivation different growing stages to the film of the demand of fertilizer under fertilizer placement drill, to change the present situation that plastic-film-covered cultivation can not topdress.

For achieving the above object, fertilizer placement drill goes out fertile mouth by interior band handle end cap by centre bore, body pipe and cone and forms under the film of the present utility model, is followed successively by inside and outside silk and connects; Body pipe middle part is established one and is advanced Fei Kou; One connecting rod is arranged in the body pipe, and the top of connecting rod is provided with spring, and small end passes band handle end cap centre bore, establishes a cross-tie on the connecting rod top, and a plug valve is established in the connecting rod lower end, and it is corresponding that the size of plug valve, position and cone go out fertile mouth inner chamber.

Go out Fei Zui, be with between the handle end cap and between connecting rod and the band handle end cap centre bore sealing ring be set all at body pipe and cone.

After adopting such structure, because being provided with cone in body pipe lower end goes out Fei Zui, little with the mulch film contact area, membrane damage is little over the ground when topdressing, the utility model simple structure is easy to make, and one man operation gets final product when topdressing, can in time implement to topdress according to the demand of crops different growing stages to nutrition.

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is the utility model structural representation.

Fertilizer placement drill under the film shown in the drawings goes out fertile mouth 3 by interior band handle end cap 1 by centre bore, body pipe 2 and cone and forms, and is followed successively by inside and outside silk and connects; Body pipe 2 middle parts are established one and are advanced fertile mouthful 4, and a connecting rod 5 is arranged in the body pipe 2, and the top of connecting rod 5 is provided with spring 7, the centre bore of band handle end cap 1 is passed in connecting rod 5 upper ends, establish a cross-tie 6 at the top of connecting rod 5, a plug valve 8 is established in connecting rod 5 lower ends, and it is corresponding that the size of plug valve 8, position and cone go out fertile mouth 3 inner chambers.

For preventing the use leakage, go out between fertile mouth 3, the band handle end cap 1 at body pipe 2 and cone, and all be provided with sealing

ring

9,10,11 between connecting rod 5 and band handle end cap 1 centre bore.

When topdressing, with the liquid fertilizer storage liquid back of the body bucket of packing into, if afterwards reinstall storage liquid back of the body bucket for solid fertilizer dissolves earlier, fertilizer placement drill advances between the fertile mouth 4 and is communicated with conduit under the outlet of storage liquid back of the body bucket bottom and the utility model film, hand-held fertilizer placement drill handle will go out fertile mouth 3 and insert soil under the film, by moving on pull bar 6 pulling connecting rods 5, the plug valve 8, fertilizer outlet is opened, and liquid fertilizer flows into soil; Releasing lever 6, connecting rod 5, plug valve 8 move down under the effect of spring 7 closes going out fertile mouth 3, and liquid fertilizer stops to flow out, and promptly finishes some fertilising.After topdressing, the ground membrane damage is very light, only stays a duck eye, still can keep its original effect.
